[Patch] (Custom query) UnicodeError: source returned bytes, but no encoding specified

[armandocroce@…]

when the component is enabled, on Custom query, I get the following error:

met this issue also in trac version 1.0.1, please fix this :(

The issue is probably seen with Genshi 0.7, similar to #11907.

I haven't reproduced the issue, but I believe the following patch would fix it:

subcomponents/web_ui.py

                     stream |= Transformer("//div[@class='field'][1]").after(self._build_renamechildren_field())
